Publication number: 20080199248Abstract: A ball and socket joint connection includes a retaining part having a fastening point and a journal slot; a ball-like component arranged in the retaining part; a rod part which is pivotable in a pivoting plane relative to the retaining part, the pivoting plane passing through the journal slot and the fastening point. A ball socket fixed to the rod part has a spherical recess in which the ball-like component is rotatably seated, a radially directed opening for receiving the ball-like component in the spherical recess, and a bearing shoulder between the spherical recess and the opening, the bearing shoulder retaining the ball-like component in the spherical recess.Type: ApplicationFiled: April 18, 2008Publication date: August 21, 2008Inventors: Paul Muders, Frank Born, Wilhelm Schwab, Andre Stein, Rolf Mintgen

Patent number: 7384209Abstract: A ball-and-socket joint connection has a retaining part which has a fastening point for fixedly mounting the retaining part to a structure, and a rod part which is arranged pivotably in a pivoting-angle region in a pivoting plane via a ball-and-socket joint on the retaining part. The fastening point and the ball-and-socket joint are situated approximately in the pivoting plane and the rod part protrudes from the ball-like component out of a journal slot which extends radially to the ball seat in a sector-like or sectional manner at least corresponding to the pivoting angle and has a width at least corresponding to the thickness of the rod part to reduce a bending moment and loading on the retaining part.Type: GrantFiled: May 11, 2004Date of Patent: June 10, 2008Assignee: Stabilus GmbHInventors: Paul Muders, Frank Born, Wilhelm Schwab, Andre Stein, Rolf Mintgen

Patent number: 7331435Abstract: A continuously blockable arresting device includes a housing and a shaft having an end received in the housing and which may be externally acted upon causing rotation thereof. The housing has a fluid-filled working space and two subchambers which can be connected to the working space. The subchambers lie next to each other. First and second pistons are guided respectively in a displaceable manner in the subchambers and can be displaced therein by a swash plate. The shaft is connected to the swash plate for rotating the swash plate. Respective control devices of the subchambers include blocking valves for respectively connecting the subchambers to the working space and passage valves for respectively connecting the working space to the subchambers.Type: GrantFiled: October 15, 2003Date of Patent: February 19, 2008Assignee: Stabilus GmbHInventors: Rolf Mintgen, Wilhelm Schwab, Paul Muders

Patent number: 7237471Abstract: A continuously lockable adjustment device for immobilizing elements which are movable relative to each other includes a stepped cylinder having a first cylinder step and a second cylinder step, the second cylinder step having a larger cross-sectional area than the first cylinder step, a stepped piston having a first piston step guided in the first cylinder step and a second piston step guided in the second cylinder step, and a piston rod connected to the piston opposite the first piston step and extending sealed off out an end of the cylinder. The cylinder has a first working space and a second working space separated by the piston and filled with a working fluid in which the piston can be displaced axially, thereby displacing working fluid from one working space to the other working space.Type: GrantFiled: March 10, 2005Date of Patent: July 3, 2007Assignee: Stabilus GmbHInventors: Rolf Mintgen, Paul Muders, Wilhelm Schwab

Patent number: 7066310Abstract: A piston is guided in an axially displaceable manner sealed off from a closed cylinder via an annular seal radially surrounding it, and divides the cylinder interior into a working space near the piston rod and a working space away from the piston rod. The two working spaces are filled with a hydraulic fluid. The piston has a one-sided piston rod which extends through the working space near the piston rod and is guided in a sealed manner to the outside through an end closing wall of the cylinder. A first valve can be opened under high pressure to connect the working space away from the piston rod to the working space near the piston rod. A second valve can be opened under high pressure to connect the working space near the piston rod to the working space away from the piston rod. A volume-equalizing chamber for receiving the amount displaced from the working space away from the piston rod, which is greater than the amount displaced from the working space near the piston rod.Type: GrantFiled: July 25, 2003Date of Patent: June 27, 2006Assignee: Stabilus GmbHInventors: Rolf Mintgen, Wilhelm Schwab, Paul Muders, Frank Born, Andre Stein

Patent number: 7048100Abstract: A piston/cylinder unit has a closed cylinder with a piston axially displaceably guided therein. The piston divides the cylinder interior into first and a second working spaces which are both filled with a fluid. A first nonreturn valve is arranged in the piston having a closing element of which is force-loaded in the closing direction. At least a portion of the first nonreturn valve is exposed to pressure in the first working space. A second nonreturn valve is also arranged in the piston and also has a closing element of which is force-loaded in the closing direction. The surface of the closing element of the first and/or second nonreturn valve acted upon by the pressure of the respective working spaces can be enlarged during the opening stroke of said nonreturn valve.Type: GrantFiled: December 12, 2003Date of Patent: May 23, 2006Assignee: Stabilus GmbHInventors: Frank Born, Rolf Mintgen, Paul Muders, Wilhelm Schwab, Andre Stein

Publication number: 20050013658Abstract: The invention is concerned with a ball-and-socket joint connection having a retaining part which has a fastening point for fixedly arranging it, and a rod part which is arranged pivotably in a pivoting-angle region in a pivoting plane via a ball-and-socket joint on the retaining part 1. The fastening point and the ball-and-socket joint are situated approximately in the pivoting plane and the rod part protrudes from the ball-like component out of a journal slot 19 which extends radially to the ball seat in a sector-like or sectional manner at least corresponding to the pivoting angle and has a width at least corresponding to the thickness of the rod part to reduce a bending moment and loading on the retaining part.Type: ApplicationFiled: May 11, 2004Publication date: January 20, 2005Inventors: Paul Muders, Frank Born, Wilhelm Schwab, Andre Stein, Rolf Mintgen

Publication number: 20040178034Abstract: A piston/cylinder unit has a closed cylinder with a piston axially displaceably guided therein. The piston divides the cylinder interior into first and a second working spaces which are both filled with a fluid. A piston rod extends through the cylinder interior and is guided on its end side to the outside in a sealed manner through a closing wall of the cylinder. Furthermore, a first nonreturn valve is arranged in the piston having a closing element of which is force-loaded in the closing direction. At least a portion of the first nonreturn valve is exposed to pressure in the first working space. When an opening pressure in the first working space exceeds an opening pressure, the first nonreturn valve is opened connecting the first working space to the second working space. A second nonreturn valve is also arranged in the piston and also has a closing element of which is force-loaded in the closing direction.Type: ApplicationFiled: December 12, 2003Publication date: September 16, 2004Applicant: Stabilus GmbHInventors: Frank Born, Rolf Mintgen, Paul Muders, Wilhelm Schwab, Andre Stein
